1. A method for supervising a control area using a detection system comprising one or more UWB detection device(s) and one or more secondary detection device(s) associated with the control area, the method comprising the steps of:
performing a first tracking process within the control area using the one or more UWB detection device(s), comprising:
successively executing ultra-wideband transmissions with UWB-enabled authentication device(s) using ultra-wideband transceiver(s) of the one or more UWB detection device(s);
determining successive positions of the UWB-enabled authentication device(s) by processing signal properties of the ultra-wideband transmissions; and
determining respective movement trajectory(s) of the UWB-enabled authentication device(s) within the control area based on their successive positions;
performing a second tracking process within the control area using one or more secondary detection device(s), comprising:
detecting occupant(s) within the control area;
determining successive positions of detected occupant(s) within the control area; and
determining respective movement trajectory(s) of detected occupant(s) within the control area based on their successive positions;
correlating the movement trajectory(s) of the UWB-enabled authentication device(s) with the movement trajectory(s) of detected occupant(s); and
generating an association of one or more UWB-enabled authentication device(s) with one or more detected occupant(s) based on the correlation.
